Gwenview does not contain PSD specific code. It relies on Qt and KDE image decoders to read different formats. You need a file named kimg_psd.so in $KDEDIR/lib/kde4/plugins/imageformats to be able to deceode PSD. It is installed when you build kdelibs.

Thank you for you advice,I found kimg_psd.so in /usr/lib/kde4/plugins/imageformats/kimg_psd.so (Archlinux). I can view PSD for example with KuickShow viewer or with Okular. Is there any other way to solve this bug? Or should I post it to a another forum?

I just tried reproduce this issue and results are strange:- Distro version of Gwenview and kdelibs (4.7.97 from Kubuntu Precise): can't read .psd- Gwenview and kdelibs from the KDE/4.8 git branch: can read .psd- Gwenview from KDE/4.8 branch and distro kdelibs: can read .psd

These results look like something was fixed in latest Gwenview, but git log shows nothing about image decoder fixes. Basically, I am puzzled, but maybe upgrading your Gwenview will fix it for you? If you are comfortable building Gwenview from git, it would be interesting to give it a try, see if the version you build can read .psd.

On my Trunk system:- Both Dolphin and Gwenview could generate a preview of the image- Gwenview could not view the PSD file- Neither Dolphin nor Gwenview showed any non-general metadata specific to the image

It looks like the thumbnailer works but somehow the image cannot be viewed - which is odd.
